Description

Technical Field

[0001] The present invention relates to a seed film produced by attaching seeds on a biodegradable film using a seed attaching machine, which can minimize seed damage, and a seeding technology in which a drip irrigation pipe and a seed film are laid on farmland by a laying machine and soil is covered thereon, thereby fixing the seed film on the farmland. The present invention relates to a seed film production device for cultivating crops using the function of the drip irrigation pipe to accurately supply water to the vicinity of the roots of crops and the evaporation inhibition function of the biodegradable film, and a seeding system including the same that minimizes water waste. Background Art

[0002] Currently, 70% of the world's groundwater and river water is used for agricultural crops, and 70% of the water consumed for crop cultivation worldwide is used for rice and wheat farming. Rice and wheat are staple foods for the largest population, and the production volume is huge. In particular, the amount of irrigation water used to produce 1 kg is also huge. According to the water footprint published by UNESCO, 3,000 liters of water are consumed to produce 1 kg of rice, and 1,350 liters of water are consumed to produce 1 kg of wheat. As the temperature in the atmosphere rises due to global warming, the amount of irrigation water will inevitably increase. Saudi Arabia, which grows wheat in a hot and dry climate, consumes 50% more irrigation water than the world average, and the amount of water consumed to produce 1 kg of wheat is about 2,000 liters. According to a research article, as climate change becomes more and more serious, the possibility of severe drought will increase 20 times, so technology that can save irrigation water is urgently needed.

[0003] As a result, efforts have been made to save water for wheat and rice. According to a 2011-14 study by ICAR-Central Agricultural Research Institute in Bhopal, India, about 310 liters of water are used to grow 1 kg of wheat using drip irrigation, which is 77% less than the global average water footprint of 1,350 liters / kg. Netafim grows rice using drip irrigation, which produces more parts and uses 70% less water than traditional rice. Drip irrigation is the most efficient of all irrigation methods and has been reported to achieve a maximum increase in yield of 100% and a maximum water saving of 40-80% (Burney. 2009; Lodhi. 2014; Kumari. 2014).

[0004] However, even drip irrigation cannot stop evaporation from farmland, so there is an irrigation method that further suppresses water waste by laying a film on top of the drip irrigation. When Q Jia (2021) compared the case of drip irrigation and soil covering with the case of covering with a film, the soil evaporation without a film and only covered with soil was 2.4 times that of the case of covering with a film. In addition, the crop yield and water use efficiency increased by about 20% and 30% respectively when drip irrigation was covered with a film compared to drip irrigation without a film. (W Zhang.2022). The above-mentioned drip irrigation method after covering with a film is widely used in cotton cultivation in Xinjiang, China. However, this method has not been adopted in other regions outside Xinjiang, China or in Xinjiang for crops other than cotton. The biggest reason is that it takes too much labor to install drip irrigation pipes under the ground film after covering with a film, and the environmental pollution problem of the plastic film remaining after farming is serious. Summary of the invention

[0005] The present invention provides a seed film production device which utilizes a seed attachment machine to attach seeds to a biodegradable film to generate a seed film, and a laying machine to spread a drip irrigation pipe and the seed film on farmland, supplying water to the vicinity of the roots of crops through the drip irrigation pipe, and suppressing evaporation with the help of the biodegradable film, thereby minimizing water waste and a seeding system comprising the same.

[0006] In order to achieve the above-mentioned purpose, the seed film supply device of the present invention includes: a cutting and bonding part, which forms a germination gap for seed attachment on the biodegradable film supplied by the covering film supply part; a seed supply part, which can put seeds into the germination gap formed by the cutting and bonding part; and a covering film laying part, which unfolds the biodegradable film with seeds attached on the farmland and covers the soil scattered by the soil flying part on the biodegradable film, and the cutting and bonding part includes: the cutting and bonding part includes: a cutting drive; a rotating piece, which is rotatably combined with the cutting drive; a shearing blade part, which is combined with the rotating piece; an adhesive supply part, which is combined with the shearing blade part to supply adhesive; and an adhesive roller, which transports the adhesive supplied from the adhesive supply part to the germination gap side formed on the biodegradable film.

[0008] The adhesive supply unit includes: an adhesive supply body; an adhesive supply path disposed at the lower portion of the adhesive supply body and functioning as a moving path for the adhesive; and a roller ball attached to the lower end of the adhesive supply path.

[0009] The covering film laying unit includes: a drip irrigation pipe supply unit; a fertilizer spreader that supplies a predetermined amount of fertilizer to the drip irrigation pipe while rotating; a plurality of roller components that are used to integrally place a seed film on the upper portion of the supplied drip irrigation pipe; and a rotary tiller that scatters soil to facilitate covering the soil on the seed film spread on the farmland.

[0010] According to the seed film production device of the present invention and the seeding system for minimizing water waste including the same, after the seed film is generated by forming a cut-and-bonded portion on the biodegradable film, i.e., the covering film, and supplying the seed film in a state of minimizing damage to the seeds, the seed film is laid on the ground and covered with soil using the soil scattering portion and the covering film laying portion, thereby being able to fix the seed film provided with a drip irrigation pipe on the ground. Thus, water can be supplied to the vicinity of the roots of crops through the drip irrigation pipe, and the evaporation of water can be suppressed by means of the biodegradable film, thereby being able to minimize water waste when cultivating crops.

The same symbols in the accompanying drawings refer to the same elements.

[0028] It should be noted that when assigning reference symbols to the technical features of each drawing, the same symbols are assigned to the same technical features as much as possible even if they are shown in different drawings. In addition, when describing the present invention, if it is judged that a detailed description of the relevant well-known structure or function may confuse the gist of the present invention, the detailed description thereof shall be omitted.

[0029] The following describes, with reference to the accompanying drawings, a device for supplying seed film by cutting the adhesive portion and applying an environmentally friendly adhesive to the covering film of the plant-derived biodegradable film supplied according to one embodiment of the present invention, and supplying it in a state that can minimize damage to the seeds using the seed attachment portion.

[0030] The seed film supply device of one embodiment of the present invention comprises: a cutting and bonding part 10, which forms a germination gap for seed attachment on the biodegradable film 1 supplied from the covering film supply part 2; a seed supply part 50, which can put seeds into the germination gap formed by the cutting and bonding part 10; and a covering film laying part 60, which spreads the biodegradable film with seeds attached on the farmland and spreads the scattered soil on the biodegradable film 1 through the rotary tiller 70 of the soil scattering part. In the present invention, the device including the cutting and bonding part 10 and the seed supply part 50 is a seed biodegradable film production device.

[0031] After the biodegradable film 1 supplied from the covering film supplying unit 2 is cut to form a germination gap by the bonding unit 10 and supplied with adhesive, the seed supplying unit 50 supplies seeds to the germination gap and then the film is rolled toward the covering film collecting unit 3. In the above process, the plurality of rotating rollers 4 can smoothly convey the covering film.

[0032] Then, the drip irrigation pipe 62 is buried under the mulch film to which the seeds are supplied by the mulch film laying unit 60 through a plurality of roller members 64 and 65 , and the soil is dispersed by the rotary tiller 70 while the fertilizer spreader 80 supplies fertilizer to the mulch film.

[0033] The present invention produces a covering film based on a plant-derived biodegradable film. Preferably, the adhesive supplied to the covering film is an environmentally friendly adhesive that does not generate volatile organic compounds (VOCs).

[0034] The cutting and bonding part 10 includes: a cutting driver 11; a rotating piece 12, which is rotatably coupled to the cutting driver 11; a shearing blade part 20, which is coupled to the rotating piece 12; an adhesive supply part 30, which is coupled to the shearing blade part 20 to supply adhesive; and an adhesive roller shaft part 40, which transports the adhesive supplied from the adhesive supply part 30 to the germination gap side formed on the biodegradable film 1.

[0035] The cutting actuator 11 includes a cylinder portion 11a and a piston rod 11b, which is connected to the cylinder portion so as to be withdrawable and reciprocating on one axis. That is, according to the operation signal of the control unit, the piston rod 11b moves in the cylinder portion 11a from the outside to the inside, thereby changing the position of the rotating piece 12.

[0036] The rotating blade 12 is formed into a triangular shape that gradually narrows from both ends of the blade surface connected to the shear blade portion 20 and the bonding roller shaft portion 40 toward the rear, and the upper end of the piston rod 11b is rotatably connected to the rear end.

[0037] The shear blade portion 20 includes a blade support portion 21 extending and coupled to the rotating piece 12 from an upper portion thereof, and a shear blade 22 disposed vertically from an outer end of the blade support portion 21 .

[0038] The adhesive supply unit 30 includes: an adhesive supply body 31 fixed to the blade support unit 21 in a vertical direction; an adhesive supply path 32 arranged at the lower part of the adhesive supply body 31 and functioning as a moving path for the adhesive; and a roller ball 33 attached to the lower end of the adhesive supply path. The roller ball 33 has a function similar to that of a ball arranged at the end of a ballpoint pen, and when the adhesive roller shaft unit 40 rotates, the adhesive located in the adhesive supply path 32 can be supplied to the adhesive roller shaft unit 40 by contacting the roller ball 33. Thus, the adhesive supplied to the outer peripheral surface of the adhesive roller shaft unit 40 is supplied to the germination gap side formed on the biodegradable film by the rotation of the adhesive roller shaft unit.

[0039] The bonding roller shaft portion 40 includes: a roller shaft support portion 41, which is extended and connected to the rotating sheet 12 from a lower part of one side; and a bonding roller shaft 42, which is rotatably connected to the roller shaft support portion 41 and supplies the adhesive supplied by the roller shaft ball 33 of the adhesive supply portion to the germination gap side formed on the biodegradable film.

[0040] The seed supply unit 50 includes: a seed supply hopper 51; a seed supply hose 52, which is connected to the lower part of the seed supply hopper 51 and transfers the seeds to the side of the germination gap formed on the biodegradable film; a seed supply nozzle 53, which is combined with the lower end of the seed supply hose 52; a seed recovery hose 54, which is connected to the upper part of the seed supply hopper 51 and can recover the seeds missed in the germination gap formed on the biodegradable film; and a seed basin 55, which is arranged at the lower end of the seed recovery hose 54 and can temporarily store the seeds that have escaped from the germination gap formed on the biodegradable film.

[0041] If some of the seeds supplied to the biodegradable film by the seed supply nozzle 52 are separated, the seeds can be recovered in time by the structure of the seed pot 55 disposed below the seed supply nozzle 53 .

[0042] The following is a description of the process of attaching seeds to a biodegradable film to produce the integrity of the seed film.

[0043] First, the cutting and bonding part 20 which descends downward to the right side at the start is rotated by the cutting driver 11 and is located in the vertical direction. Then, the rolled biodegradable film reel is loosened in the covering film supply part 2, and a germination gap is formed by the shear blade 22, and an environmentally friendly adhesive is applied between the germination gaps formed by the shear blade part by the adhesive supply part 30. Here, the adhesive is supplied by a roller ball 33 in the shape of a ballpoint pen. In order to minimize seed damage, the seeds are transported and supplied to the pots through the seed supply hose 52 and the seed supply nozzle 53.

[0044] Seeds are sprinkled on the part where the adhesive is applied by the adhesive supply unit 30 to make them adhere, and the seeds that fail to adhere are recovered again through the seed basin and the seed recovery hose by air inflow.

[0045] The covering film laying part 60 includes: a drip irrigation pipe supply part 61; an upper alignment roller 63, which performs a one-time pre-alignment operation on the drip irrigation pipe 62 loosened from the drip irrigation pipe supply part; a fertilizer spreader 80, which supplies a predetermined amount of fertilizer to the drip irrigation pipe while rotating; a fertilizer supply pipeline 67, which is connected and arranged at the lower end of the fertilizer spreader 80 and accommodates the drip irrigation pipe 62 inside; a plurality of roller components 64, 65, which are used to integrally place the seed film on the upper part of the supplied drip irrigation pipe; and a rotary tiller 70, which facilitates the digging of soil in the farmland to disperse the soil and facilitates the spreading of the seed film on the farmland.

[0046] The plurality of roller members 64, 65 include a touch roller 64 that guides the initial layering between the drip irrigation pipe 62 for fertilization through the fertilizer supply line 67 and the supplied seed film, and an unfolding roller 65 that stably spreads the combination of the layered seed film and the drip irrigation pipe on the farmland.

[0047] The following describes a process of laying a biodegradable film with seeds attached thereto on a farmland using a laying machine towed by a tractor (T).

[0048] First, the drip irrigation pipe 62 released from the drip irrigation pipe supply unit 61 is pre-aligned, and a predetermined amount of fertilizer is delivered to the drip irrigation pipe 62 by the fertilizer applicator 80 .

[0049] The seed film is spread out on the farmland and the drip irrigation pipe is buried under the seed film. At this time, the drip irrigation pipe 62 is located below the seed film through the lower touch roller 64 while passing through the upper aligning roller 63.

[0050] In order to lay the seed film and the drip irrigation pipe in an integrated state, at the same time, the seed film passes through the unwinding roller 65. The fertilizer side strip application (band application of fertilizers) is performed under the seed film.

[0051] The seed film deposited on the drip irrigation pipe is spread on the farmland, and the soil dug up from the farmland by the rotary tiller is covered on the seed film. Here, in order to facilitate the digging of the soil on the farmland, the soil scattering plate is overlapped perpendicular to the rotation direction of the rotary tiller to facilitate the scattering of the soil.

[0052] The seed film production device of the present invention generates seed film by cutting the bonding part and coating the environmentally friendly adhesive on the supplied plant-derived biodegradable film, ie, the covering film, and supplying the seed film in a state of minimizing the damage of the seeds using a seed attaching machine.
